Covalent Streptavidin - 30nm Gold Conjugate

Covalent Streptavidin - 30nm Gold Conjugate for gold nanoparticle labelling

Covalent Streptavidin - 30nm Gold Conjugate supports method development where biotinylated antibodies, probes and capture molecules must be detected in Immunoblotting, Light Microscopy and Electron Microscopy. It helps researchers evaluate target fit, assay readout and control strategy before selecting a related label or antibody format.

Scientific fit

The covalent streptavidin format is selected for biotin-based detection workflows where a robust linkage to the gold label is important. This mid-sized gold particle is a practical choice when both particle visibility and access to the labelled target must be balanced.

Protocol notes

• Fits workflows that require clear Covalent Streptavidin detection and a reagent choice that can be documented consistently.
• Useful when a biotinylated antibody, oligonucleotide or ligand should be converted into a nanoparticle-visible signal.
• Include matched negative controls and optimize blocking to separate true target-associated signal from nonspecific particle binding.
